PUMP.

SPECIFICATION forming' part 'Of Letters Patent NO. 253,247, dated February 7, 1882.

Application lcd May 31, 1881. (No model.)

To all whom trudy concern Be it known that I, THoMAs V. WARNER, ot' Waukegan, in the county ofLake and State ofIllinois, have invented certain Improvements in Pumps, ot' which the following is a specilication.

This invention relates to the construction of well and cistern pumps; and it consists in the novel combination and manner of construction of the several parts, as hereinafter fully set forth. Y g The accompanying drawings, which form a part of this specicatiomshow at Figure l a plan view of the pumping-cylinders with the top-protecting plate removed 5 at Fig. 2, an end view, partly in section, of the same parts; at Fig. 3, a horizontal section of the same upon the line as, Fig. 2; at'Fig. 4, an elevation of the handles and spout at the upper end ofthe pump or main tube; at Fig. 5, an exterior view of 011e of the cylinders; and at Fig. 6, a crosssection of the same upon the line 3/ y, Fig. 5; and at Fig. 7, a section of the main' tube.

Like letters indicate like parts in all the gures where they appear. l

A A are two parallel cylinders, placed horizontally at the bottom of the well or cistern. Each ot' these cylinders has acentralinletport, c, and a central filling-piece, a', located directly under the inlet, and dividing the cylinder into two parts, and I call them double cylinders,7 because they are thus divided. The tillingpiece leaves a square openinginto each part of the cylinder from the inlet-port, (shown in dotted lines at Fig. 6,) and .such openingis lled or covered by a hinged or iap valve, c2. Two reciprocating pistons or plungers, B B', are inserted in each ot the cylindersA, one plunger at each end and upon either side of the inlet-port. Extending from each halfor par-tof the cylinder to the corresponding half ot' the other cylinder is a cross-passage, O, each cross-passage containing a ball-valve, c', whereby it maly be alternately opened and closed at each en(` In practice I place between the two cylinders a block, D, which supports them, and cut these passages in'said block; but it the. block is not used, tubes may be specially provided for the purpose. An uprighttube,E, is stepped in this block, or otherwise supported, and openings e into it from each of the crosspassages are provided.

The plungers are reciprocated by a pinion, F, encircling the tube E, and racks Gr, meshing with said pinion and rigidly connected at each end with the outer end of one of the plungers by a depending piece, g, and screws g. The upper portion of the cylinder is cut away at each end, as at g2, to give the necessary room for reciprocation. The pinion F is secured upon the foot of the up-ilow pipe H, which is placed over the tube E sleeve-fashion, so that the latter acts as a pivot upon which the tube H may be turned. At the top,

or above ground, the tube H is provided withl one or more laterally-projectie g arms, h, Whereby it may be swung or semi-rotated, and a spout, It', which may be loose thereon, and held by some stationary device, so it will remain still during the semi-rotation of the main tube. A bearing will naturally be provided for the tube near the point where power is applied to it, if it is so long as to need such.

Aball, I, is inserted in the main tube to serve as a valve, with the top of tube E for its 'seat' It prevents th'e water which may be above it in the tube from iowing back. It is confined to a limited upward movement by the cross-pin z'. By the use of a valve at this point the pump is always made ready for instant service, and water may be drawn with the tirst strokes of the handles.

A covering-plate, J, is preferably employed to prevent injury to the working parts by the fallin g thereon of material from above, and to keep .the gears clear. A bottom piece, K, is also used to strengthen and support the parts.

.With the pump thus constructed the operation is as follows: With each motion of the which has gained access to the interior ot' the cylinders between them and the valves a2, which hangin and close the inlet-openingsinto their parts or ends of the cylinders, and such pressure instantly closes said valves and pre- IOO Vwhich the plungers are moved away from the inlet-the outside pressure of Water opens the valves a2 and rushes in and lls any vacant space in those part-s ofthe cylinder due to the retreat of the plungers. NVhen the movement of the semi-rotating parts is reversed the operation just described as taking place in the parts ofthe cylinder holding' the plunger B and their connecting passages is duplicated in the parts holding the plungers B and their connections, and the operation of filling ascrihed to the latter (cylinders B) is duplicated in former, (cylinders 13,) and so on. The two sets ot' plungers alternate with each other with each reversal of the movement of the actuating;- devices.

'lhe pumping devices are secured iu the Well by stakes driven into the earth, or in any other appropriate way. The plungers should displace as little water as possible, and hence I hollow out the inner ends at b, as shown.

I claim- The combination, with the plungers and the up-tiow tuhe, of the pinion and racks, whereby the semi-rotation of the tube is caused to reciprocate the plungers and the tube to serve` Witnesses:
